Yibin steel structure: steel tower mast structure is one of the steel structure special steel structure, tower mast structure includes transmission tower, radio pole, TV mast, TV tower and other towering engineering structures, which are characterized by large height, small section, construction should choose special mechanical equipment and lifting methods for installation.

Masts and towers differ in construction and installation methods. Generally speaking, masts have a large installation site, and the weight is light, the section is small, and the structure is simple, so the installation is relatively simple. The tower does not necessarily have enough installation space, and the cross-section is large, the structure is more complex, and the installation is more difficult.

The

commonly used lifting methods of tower mast structure are: high-altitude assembly method in sections, high-altitude assembly method and high-altitude assembly method of sub-sections all need to use crawling cranes, and attachment tower cranes can also be used.

1. The

high-altitude assembly method is used to hoist masts with small cross-sections. The crawling crane or crawling mast is mostly supported on the pillars on the side of the mast, and will be hoisted and installed section by section after enlarged assembly on the ground, while the crawling crane or crawling mast also climbs upwards with the height of the mast.

2. The

high-altitude assembly method is used to lift the mast and tower structure with a large cross-section, with single equipment, simple process and high work efficiency. The lifting equipment used in this method mostly uses crawling poles.

3. The overall lifting method is to assemble the entire structure on the ground before lifting, and then use the rod or herringbone rod to take the temporary hinge support as the fulcrum, and rotate the tower mast structure around the hinge support and erect it through the start of the hoist and pulley line.
